FALLEIt-BAR.

To all fLUhOflt it may concern. 1

Be it known that I, WILLIE HoLDswoR'rH, asubject of the'King of 'England, having declared my intention of becoming acitizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented .a new and useful Faller-Bar, of which the following is a specification.

This invention relates to a faller bar for use on gill drawing frames.

The principal objects of the invention are to provide a faller bar of this character which can be made by unskilled labor instead of the specialists now necessary and yet will be more durable than those heretofore made; which-will have its pinsso arranged that they cannot fall out in the only way in which they now'fall out in practice, that is through the back; which will be so constructed that the pins can be made of.

different construction than cylindrical, which is now the universal shape so that they will have greater strength; which will be so made that the bar itself can be materially thicker so as to increase its strength;

which will be cheaper because shorter pins can be -used; andwhich can be repinned very easily either with pins of the same size and shape or with different ones and different numbers to the inch, thus materially economizing in the first cost and particularly in the cost of maintenance.

- faller bar partly in'section;

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which- 7 Figure 1 is a plan of part of a gill drawing frame showing the faller or 'gill bar the position it assumes'when it comes up between the end of the saddle and disk and illustrating it in connection with the gill bar frame which is the subject of the patent to William Holdsworth, No. 722,984;

Fig. '2 is aside elevation ofthe same showing the top and bottom screws with my improved faller bars in section;

Fig. 3 is a side view of my improved Fig. 4 is a sectional view on the line 44 of Fig. 3;

ing a pair ,of pins in the act of being introduced. v For the purpose of illustration I have Patented Feb. 3. 1920.

shown the inventionas applied to the gill drawing frame illustrated in thcabove mentioned patent to William Holdsgworth. But it is to be understood that the invention is not limited to that particular type of draw- The invention itself. lies entirely in the taller bar and not .in any novelty. of its association with the rest of the parts of the frame. This faller bar as will be understood from reference to the above mentioned patent is moved through a path of substantially rectangular form. It is moved longitudinallybythe screws 1 and 5 raised by the cam 3 from the screw 1 upv to the screw 5 and passes around the sad dle 7 described, dropping by the cam' atthe end of the screw 5 that is not shown in Fig. 2.

These faller bars as heretofore constructed are made by highly' specialized mechanics who receive pay alliout of proportion to the difliculty'of their work and. yet it is a trade that has to be learned by experience because the faller bars are bored to gage so as to set the pins at the rate of twelve to sixteen per inch in aspace eight or ten inches long The pins are made of wlre of such size that the holes into which they are inserted are very close together and have to be drilled with care. These holes extend clear through the faller bars and in order to avoid having the holes too longthe faller bars. have to be made of smaller cross section than is otherwise desirable. Consequently they frequently break. Furthermore the pins drop out through the back during use thus necessitating their replace ment at frequent intervals. These difliculties are all. overcome by this invention as will appear. These advantages are secured in a very simple manner.

IThc faller bar 10 is made at the ends the I l same as it is now sothat it can be guided in a proper manner as above. mentioned, but its shank is made of greater depth than has been the case heretofore and instead of boring through it to provide holes for the pins it is provided with a longitudinal .groove or recess 11 in the upper side passing only part way through it. For example in some cases this groove will be only fiths or ths of an inch deep. The sides of this groove and bottom are made plain. In this groove fits with-.adriving-fit a lockingbar 12. This locking bar is provided with parallel depressions 13 on its opposite sides. These are the two sides of this locking bar are made-- alike, except that where there is a space on one side preferably there is a projection between two spaces on the other directly opposite it. The pins are placed by in the several notches v .1 depressions in the locking bar and lean against the sides .of the faller b ar as indicated in Fig. 6 and then the locking bar 12 is driven in so 8 to force the pins-to a perfectly straight and parallel pos t onand firmly ock he n pl ce- It will be seen that the butts of the pins are considerably shorter-than has been; the case heretofore. Consequently there is a material saving in the amount of wire used.

Furthermore there is nov possibility ofthe ,inscoming out through the bottom aswill c obvious.

In 7 the old constructions the continual dropping of the'faller bar on a solid" surface tended toloosen' the pins and they always eventually began. to come out at the bottom. This Iavoid, thus reducing the ex eas or maintenan e j ery. mater al yurthermore the faller barcan berepinned very easily and in doing so it. is not necessaryto repin it with p ns of thesame size orthe same pitch. Merely by changing the.

loc 7 bar 12 these elemehts can bechan ed accor 'lngly. Furthermore the bar itsel is much deepe nd cker th ni has been heretofore, and it isstronger so as to better withstand the usage to which it .is put. The

. pins also not have to, be cylindrica t then butts but canbe squa-re,tr1a-ngular or of; any th r es eds p t s ur he great sts rength- Wh n i des re totake h pins out, ejectors are. introduced in three perforations 1,5 extending fromthe bOttOm of 'the socket L1 to th 'bottom (of the falls bar- Th y are dr tsninto rce out he f ller ar 2- 1 -.A1th0ugh I ve llu t ate s ibed onl'yha single. fo m of th in en n nd hown i a pp ied to a sin e r of d aw ing frame, I am aware 0ft ef act that I Odi fie ion can be ma e in i and e Pr n pl canbe applied, to other types ofdrawlnm f mes, i ho t ep r ing'fli m e COPQ the invention as expressed in the claims.
